Isuzu MU-X vs Audi Q3

What's the difference?

The MU-X has always had plenty of appeal as a daily driver – dependable, not dynamic – and it’s a proven 4WD wagon.

Some people don't like the noisy, sluggish engine, but I don't mind it because it delivers off-road.

There was already a lot to like about the seven-seater wagon in terms of its off-road capability, driver-assist tech, standard features, and simple all-round driveability, and the X-Terrain – which encompasses all of that AND adds some polish to the mix – is an impressive top-shelf addition to the MU-X line-up. Even if it's so pricey...

The Audi Q3 Sportback S line 40 TFSI quattro is a quiet achiever.

Not as flashy or performance driven as some of its rivals, it still manages to tick almost every box when it comes to comfort and features. Like most models in the class, space in the back seat is modest but for a top-spec non-performance model, the price is alright and it’s lovely to drive.

As I’ve said before, the MU-X has never been particularly exciting or boring in terms of design, just comfortably adopting a low-key, middle-of-the-road type design – sales gold, in other words.

But the X-Terrain has distinctive ‘X’ branding here and there – inside and out – and that adds a subtle class to this variant.

The X-Terrain is 4860mm long (with a 2855mm wheelbase), 1870mm wide (excluding mirrors), 1825mm high and has a listed kerb weight of 2195kg.

It has a wheel track of 1570mm and an 11.6m turning circle. 

Our test vehicle has the exclusive X-Terrain paint – slate grey metallic – which matches well with the X badging, bigger grille design, new headlights, three-tier LED tail-lights, and redesigned wheels.

The interior strikes a stylish note as well with red stitching on the dash, centre console and leather-accented seat trim.

The Q3 Sportback blends the practicality of an SUV with a sports-car presence due to its wide 2022mm stance and coupe-styled rear. With the black accents across the body, big 20-inch alloys and sharp Matrix LED headlights, the Q3 Sportback more than holds its own against the sporty prowess of its rivals.

The cabin establishes that it sits within the premium market with its leather mix upholstery and flashy-looking tech that headlines an angular dashboard. However, it's understated compared to its rivals, which all boast a stronger cabin presence.

Overall, it's not a ‘look at me car’ but the longer you look, the better it gets.

The interior has a pleasant, familiar and practical feel about it and this is an easy space in which to swiftly become comfortable. 

Controls are easy to locate and operate and charging options are numerous – a mix of USB-A, USB-C and 12V up front, and USB-A for the second row.

Storage places include recesses for your everyday carry gear, a suitably deep centre console, as well as dual cupholders up front, cupholders in the rear fold-down centre armrest and bottle holders in the doors.

There are cupholders either side of the third row in the MU-X for passengers riding back there.

The MU-X has physical-button options to activate some functions (including to switch on the audio system, to adjust volume, access sat nav etc).

Seats are adequately comfortable and supportive through all three rows – yes, even the third row is roomy enough to prevent whining from whoever is stuck back there.

The cargo area is 311 litres with all three rows in use, 1119L with the third row flat and 2138L with the second and third rows folded.

The rear cargo area has a cargo cover, tie-down points, a 12V power outlet, a storage space under the rear cargo area floor and a space for tools inside the driver’s side rear cargo wall.

The Q3 Sportback offers plenty of head- and legroom up front, with access that is accommodating because of the wider door apertures.

Like its rivals, the back seat offers modest space for my 168cm height, but it might be a squeeze if you taller. The middle seat suffers the most with legroom due to the tall transmission tunnel – keep this seat for kids only.

However, all other seats offer well-rounded comfort with decent-padding, side bolsters and the front get extendable under-thigh and lumbar supports, as well as heat functions.

The rear row also gets directional air vents, reading lights, two USB-C ports and a 12-volt socket. Longer trips will be comfortable for four occupants but five will elicit some grumbles.

Storage is good for the class with a glovebox that can fit a manual, a medium-sized middle console and a large phone tray. There are four cupholders and four drink-bottle holders throughout the car, and the rear row also get two map pockets.

The boot offers class leading space with its 530L capacity and only the BMW X2 beats it (by 30L). Storage options open up again with the 40/20/40 split of the rear row. The top model gets a powered tailgate with gesture control and temporary spare tyre.

Technology looks high-end and the touchscreen multimedia system is easy enough to use once you get your head around the menus. The built-in satellite navigation is top notch and the directions are pulled through to the digital instrument cluster.

The Q3 now gets wired/wireless Apple CarPlay and wired Android Auto. The CarPlay maintained a steady connection this week. Charging options are great with a total of four USB--C ports, two 12-volt sockets and a wireless charging pad to choose from.

There are four variants for the Q3 before you hit the high-performance model, and our test vehicle is the top S line 40 TFSI quattro model, which is priced from $70,800, plus on-road costs, making it the most affordable compared to its rivals.

Its closest rival is the Lexus UX300h AWD F Sport with a price tag of $73,210, then the BMW X2 20i M Sport at $75,900, and the Mercedes-Benz GLA 250 4Matic sits at the top at $79,700.

Our test vehicle has also been fitted with an upgraded Sonos 3D surround sound system and sunroof for an additional $3900.

As one would expect for a top model, the S line is well-equipped and includes electric and heated front seats, leather upholstery and high-end technology throughout, which includes a 10.1-inch touchscreen multimedia system, a 12.3-inch digital instrument cluster, satellite navigation, wireless Apple CarPlay, wired Android Auto, Audi Connect app with over-the-air updates, four USB-C ports, a 12-volt socket and a wireless charging pad.

Practical features include keyless entry and start, adaptive LED headlights, a frameless auto-dimming rearview mirror, rain-sensing wipers, a powered tailgate (with gesture control) and a park assist feature.

It's features list mostly mirrors that of its rivals, but it does miss out on ventilated front seats.

The MU-X has a 3.0-litre four-cylinder turbo-diesel engine, producing 140kW and 450Nm and it’s matched to a six-speed auto.

These form part of a proven powertrain and while the MU-X may not be the most dynamic vehicle to drive – it’s acceleration is sluggish rather than punchy – it has a real tractability that nullifies any other niggles.

It has part-time 4WD, with high- and low-range as well as various drive modes, rough terrain mode, and a rear diff lock.

Our test vehicle keeps it's tried and tested 2.0-litre four-cylinder turbo-petrol engine, which produces 132kW of power and 320Nm of torque. Those outputs are slightly less than most of its nearest rivals and it sports a slower sprint time of 7.8 seconds.

The Q3 Sportback is a quattro, which means it has an all-wheel drive and it boasts a silky-smooth seven-speed auto transmission.

While it doesn't induce strong sports-car vibes on road, it’s not a car you'd ever have the audacity to call slow.

Official fuel consumption for this MU-X is 8.3L/100km and that's on a combined cycle. 

On this test I recorded 10.2L/100km. I did a lot of high and low-range four-wheel driving, so that fuel consumption is not too shabby.

The MU-X has an 80-litre fuel tank, so going by my on-test fuel consumption figures you could reasonably expect a driving range of about 784km from a full tank. 

The official combined fuel cycle figure is 8.2L/100km, but the real-world usage is at 8.6L after doing a mix of open-road and urban driving. Considering the lack of restraint shown for really giving this model a real 'go' on the open-road, the fuel usage is respectable.

Based on the official combined fuel cycle and 60L fuel tank, you should see a theoretical driving range of up to 732km, which is good for any longer road trips you might want to tackle.

In previous tests, the MU-X has been fine on road and more than adequate on gravel, dirt tracks, and during low-range 4WDing. But it’s been a jarring, skippy ride on irregular surfaces rather than as composed as it could – and should – have been. The culprit? Firm suspension, over-inflated tyres, too-tight trousers, who knows?

The good news is it seems like Isuzu has ironed out any issues in the suspension, minor or otherwise, because the MU-X is now is a lot better in terms of ride and handling than ever before. 

Off-road, the MU-X has always been a proven combination of its 3.0-litre, four-cylinder turbo-diesel engine, clever six-speed automatic transmission, and an off-road traction control system that's been increasingly well recalibrated through a number of generations. 

The engine is tractable and gruff, it has plenty of grunt and, as long as you're not driving like a complete hoon, you can usually get through most obstacles without a lot of fuss.

It's this mix of mechanicals and driver-assist tech that make the MU-X such an effective 4WD package. And there are a number of reasons for that. 

For one, that engine delivers plenty of torque down low and in the mid-range torque and that's crucial for four-wheel driving. 

And another thing, Rough Terrain Mode – like a beefed-up and fine-tuned off-road traction control – proves very effective because it punches torque to the wheel with the most traction – while wheel spin on tyres that aren't touching dirt is minimised – and that way it keeps the vehicle moving through obstacles with safe and controlled momentum. 

As I’ve noted before though, Rough Terrain Mode is not a magic all-conquering solution, but it is another handy addition to the MU-X’s off-road toolbox.

And the MU-X also has a rear diff lock to back you up – and that's another valuable component. 

The MU-X has approach, departure and ramp-over angles of 29.2, 26.4 and 23.1 respectively.

A listed 235mm of ground clearance is about standard for this kind of wagon but, as I’ve said before, it seems vulnerable in the underbody, side steps and its plastic mud guards. So the underbody may touch dirt, depending on how challenging the terrain is. 

Wading depth is listed as 800mm.

But, as always, with focused driving, you’ll have lots of fun and you'll minimise any superficial damage or scuff marks to the MU-X.

The MU-X has plenty of potential as a touring platform, but, if you’re planning to do any off-roading beyond well-maintained tracks, then get rid of its road-biased tyres and replace them with all-terrain tyres.

The showroom-standard tyres on this MU-X – 265/50R20 Bridgestone Dueler HTs – are okay, but not really up to scratch if tough 4WDing is what you’re keen to do. I’d prefer an 18-inch wheel and tyre package with decent all-terrains.

The MU-X has a full-sized underslung spare and in terms of packability, the MU-X X-Terrain has a listed payload of 605kg, GVM is 2800kg and GCM is 5900kg.

If you are considering using your MUX as a tow vehicle, it's handy to know that it can legally tow 750kg (unbraked) and 3500kg (braked), which is the standard for large four-wheel-drive wagons. 

Be aware though that, as with any other vehicles, once you're towing anywhere near the maximum weight, your payload is greatly reduced.

The power delivery for the Q3 Sportback S line model is effortless. It doesn’t have the thrum or burbling of a turbo, but the power is well and truly there whenever you need it. So, while not as ‘powerful’ as some of its rivals, you don’t feel like you’re missing out.

The low and wide stance of the Q3 Sportback translates to nimble and direct handling – you can take corners at speed with almost no roll and the steering sits within the goldilocks zone for firmness.

A downside is the cabin noise, which is fairly loud with road and wind no matter the speed – but you don't have to raise your voice. You'd expect a bit of noise with the big wheels, but you always hope for more refinement at this grade level.

The Q3 isn’t difficult to park, but it does take a moment to get your bearings on how it fits a space, as it’s bigger than you might expect. The 360-degree camera is super clear, which takes out a lot of the guesswork.

The car feels like an extension of you as a driver which elevates the overall on-road experience despite not being a performance model. This would be well-suited for a driver who wants great on-road performance without feeling like someone who is in a mid-life crisis.

The Q3 has a maximum five-star ANCAP safety rating from testing done in 2018 and it scored highly with the adult protection score sitting at 95 per cent, child protection score at 88 per cent, and safety assist systems score at 85 per cent, and it's vulnerable road sits at 76 per cent.

Unfortunately, the Q3 only features six airbags, which is fairly low for this day and age and misses out on a front centre airbag.

Standard safety equipment is robust and includes blind-spot monitoring, driver attention alert, a First Aid kit, a warning triangle, tyre pressure monitoring, rear cross-traffic alert, lane keeping aid, lane departure alert, traffic sign recognition, intelligent seatbelt warning, adaptive cruise control with stop/go function, park assist, a 360-degree camera and front and rear parking sensors.

There are two ISOFIX child seat mounts and three top tethers but two seats will fit best.

The Q3 has AEB and forward collision warning with car, pedestrian and cyclist detection. This system is operational from 5-85km/h (and up to 250km/h for car detection).

The MU-X has a six-year/150,000km warranty and seven years of roadside assistance. That warranty is okay in terms of years, but unlimited kilometres would be welcome.

Service intervals are scheduled for every 12 months or 15,000km, whichever occurs soonest. 

Capped-price servicing covers the first five scheduled services for 24MY and later vehicle models (up to five years/75,000km, whichever occurs first) – at a cost of $469 for each service.

The Q3 comes with a five-year/unlimited-km warranty, which is a normal term for the class.

You can pre-purchase a five-year servicing plan, which costs $3330 overall, or $666 per service which is competitive for the premium segment.

Servicing intervals are reasonable at every 12 months or 15,000km whichever occurs first.
